JOHN HOWARD, OF CROSBY, ENGLAND.

STEAM SEPARATQR.

' 7 Application filed. April 22, 1924. Serial No. 708,195.

To all whom it may concern:

Be it known that I, JOHN HOWARD, a subjcct of the King of Great Britain,residing in Crosby, in the county of Lancaster and Kingdom of England,have invented certaln new and useful Improvements in and Relating toSteam Separators, of which the following is a specification.

This invention relates to improvements in steam separators. It is theobject of the invention to provide a device which is particularlysuitable for use in connection with steam whistles.

The invention consists in a steam separator which is mounted immediatelyadjacent to the valve of the whistle instead of adjacent the boiler orat other remote points. The invention further consists in a steamseparator employed for use in connection with steam whistles or the likeapparatus in which a curved pipe is employed from the inner wall ofwhich a steam pipe is co-n nected substantially at right angles so thatthe separated water follows the direction of the curved pipe while thesteam passes through a vertical pipe to the whistle.

The invention is more particularly de scribed with reference to theaccompanying drawings, in which Figure 1 is an outside elevation of thedevice.

Figure 2 is a corresponding plan view.

Figure 3 is a sectional view on the line AA of Fig. 2.

In the preferred form of the invention shown in the drawings, the devicecomprises a semi-circular or otherwise curved pipe 1 mounted on theflange 2 of the usual stop valve 3 for passing steam to a whistle orother device fitted to the flange end 1. It will be seen that thissemicircular pipe 1 slopes downwards from the inlet end at-the top of ashort vertical extension 5 to the outlet 6 to the flange 7 to which areceptacle for condensed steam in the form of a trap drain or otherdevice is connected as shown at 11. Furthermore, this pipe 1 graduallytapers downfrom the inlet to the outlet 6.

Steam is led ofi' by an upwardly inclined connect-ion 8, leading away atright angles to the path of fluid through the pipe 1 and then again awayat an angle to the horizontal to be connected to the whistle or otherdevice by the flange 4. As water may collect by the condensation ofsteam between the top of the extension pipe 5 and the valve in the chest3, this may be drained away by a small drain pipe, such as indicated indotted lines at 9, which may further be provided with a needle or thelike valve 10.

This device meets the ditficulty caused by sudden blowing forward of alarge volume of condensed water in that the condensed water. is carriedpast the vertical pipe to the drain while the steam rises through thevertical pipe. By placing the device in proximity to the whistle, theseparator also deals with water which is condensed in the length of thepipe lying between the boiler and the whistle, or other device.

I declare that what I claim is 1. A steam separator comprising a trapfor condensate, a curved pipe leading steam and condensate towards saidtrap and a pipe for dry steam leading from said curved pipe and inclinedtowards the centre of curvature of the curved pipe. 7

2. A steam separator comprising a trap for condensate, a curved pipeleading steam and condensate towards said trap, and a pipe for dry steamleading upwardly from said curved pipe and inclined towards the centreof curvature of said curved pipe.

3. A steam separator comprising a trap for condensate an eccentricallycurved pipe leading steam and condensate towards said trap and a pipefor dry steam leading upwardly from said curved pipe and inclinedinwardly of said curved pipe.

4. A steam separator comprising a trap for condensate, a curved pipeinclined downwardly from inlet to outlet leading steam and condensatetowards said trap and a pipe for dry steam, leading from said curvedpipe, situated intermediate the ends of the path of flow of condensatein said curved pipe.

5. A steam separator comprising a trap for condensate, a curved pipeinclined downwardly from inlet to outlet leading steam and condensatetowards said trap and a pipe for dry steam, leading from said curvedpipe and inclined towards the centre of curvature of the curved pipe.

6. A steam separator comprising a trap for condensate, a curved pipeinclined downwardly from inlet to outlet and reduced in diameter towardsthe. outlet, leading steam and condensate towards said trap and a pipefor dry steam, leading from said curved pipe situated intermediate theends of the path of flow' of condensate in said curved a pipe.

7. A steam separatorcomprising atrap for condensate, a curved pipeinclined downwardly from inlet to outlet and'reduced' in diametertowards the outlet leading steam and condensate towards said trap and apipe for dry steam, leading from said curved pipe and inclined towardsthe centre of curvature of the curved pipe.

=In witness :whereof, I have hereunto signed any name this 11th day ofApril, l924 in the presence of two subscribing witnesses.
